The Pittsburgh Penguins clinched their fourth Stanley Cup championship over the San Jose Sharks on Sunday night.

And Seth Meyers' three-month-old son Ashe celebrated the landslide win in an extra special way the next day, making his Instagram debut on his proud dad's social media page wearing a black and gold Penguins onesie.

The smiling baby happily posed for the photo, looking cute while sitting upright on a couch.

'I'm not the biggest hockey fan but thanks to the many Meyers who call Pittsburgh home my son got to dress like a champion this morning,' the Late Night host wrote alongside the photo.

'Hopefully it's the first of many for him and his inherited teams.'

Though the 42-year-old might have not grown up in Pittsburgh, Seth's father is a proud native and Seth himself is an outspoken fan of the Pittsburgh Steelers and Pittsburgh Pirates.

A major sports junkie, Meyers also roots for the Boston Red Sox and Boston Celtics.

He made sure to shout out these teams on the Instagram post, hashtagging '#steelers #redsox #pirates #celtics #westhamunited #knvb #northwestern,' references to his alma mater, Northwestern University, as well as the Dutch national football team and the English football league.

Ashe is Seth's first son with wife and human rights attorney Alexi Ashe, who he married in 2013 after five years of dating.

After welcoming their bundle of joy in late March, the comedian shared with viewers during a Late Night episode the heartwarming story behind Ashe's name.

'We named our son Ashe, which is my wife's maiden name, and I cant picture a better way to honor what my wife did than by naming him after her.

'The middle name is Olsen, which is my mothers maiden name. And to be able to name him after those two women...' Meyers said before turning his head as he became choked up with emotion.
